The male-side protruding portion 3 of the male connecting portion 2 is inserted and the construction is performed in the same manner.

(Embodiment) FIGS. 1 to 5 show an embodiment of the present invention, in which 1 is a surface material of an interior / exterior plate, and a strip of metal, synthetic resin, aluminum or the like having a required width and length. Are appropriately formed by press working, roll working, extrusion molding, etc. Reference numeral 2 is a male connecting portion formed on one side edge of the surface material 1 in the longitudinal direction, and 3 is a male member having a heat insulating material filling void portion 3a integrally formed with the male connecting portion. It is a side protrusion. Reference numeral 4 denotes a female connecting portion formed on the other longitudinal edge of the surface material 1 , which is a concave groove portion 5 into which the male protruding portion 3 can be fitted, and the male protruding portion at the end of fitting. A female side protruding portion which is in a superposed state on the portion 3 and covers the male side protruding portion 3 and which has a heat insulating material filling cavity 4a which is thinner than the male side protruding portion 3.
5a is integrally bent.

6 is a nail striking extension formed on the male connecting portion 2;
Is a smooth convex arcuate surface of the same shape provided in a required number in parallel with the longitudinal direction on the surface 1a portion of the surface material between the male and female connecting portions 2 and 4, and FIG. As shown in the figure, the number of the semi-cylindrical smooth convex arc surface 7 in cross section is arbitrary, and the curvature of the semi-cylindrical smooth convex arc surface 7 in cross section is also arbitrary. 7a is a concave portion between each of the above-mentioned cross-sectionally kamaboko-shaped smooth convex arc surfaces 7,
It is formed with a curved surface in cross section, and is located below the male and female side projecting portions 3 and 5a of the male and female connecting portions 2 and 4.

Reference numeral 8 denotes a space on the back side of the surface material 1 , which can be filled with styrofoam, urethane foam, gypsum, asbestos and other required heat insulating material 9 as required. 10 is a backing material, which is an aluminum foil sheet, waterproof, non-combustible cardboard, or the like. 11
Is the main pillar, studs, furrows and other wall foundations.

(Effects) As described above, according to the present invention, the male-side protrusion having the required length having the space for filling the heat insulating material on the both longitudinal edges of the surface material made of the strip having the required width and the required length is provided. Section and a nail striking extension are integrally bent to form a male type connecting portion, a concave groove portion into which the male side protruding portion can be fitted, and a superposed state on the male side protruding portion at the end of fitting. And a female connecting portion formed by integrally bending the female protruding portion that covers the male protruding portion and further has a heat insulating material filling cavity that is thinner than the male protruding portion. And the male,
The surface material decorative surface between the female mold connecting portions is formed into the same number of semi-cylindrical smooth convex arc surfaces that are parallel to each other in the longitudinal direction, and the concave portions between the respective semi-cylindrical smooth convex arc surfaces are curved surfaces in cross section. In addition, since the surface material is formed at a position lower than the male and female protruding portions of the male and female connecting portions, the entire surface material has the same shape of a semi-cylindrical smooth convex cross section parallel to the longitudinal direction by the required number. The concave portion formed on the arc surface and having the same shape as the semi-cylindrical smooth convex arc surface has a curved surface in cross section, and is formed below the male and female side protruding portions of the surface material. As a result, the concave portion is deep-drawn and the strength as a whole is considerably reinforced, and when the decorative surface is impacted from the outside by the cross-section kamaboko type smooth convex arc surface and the curved surface of the concave portion. Disperses the impact force and sufficiently deforms the surface material In addition to being able to prevent it, it is easy to process with a press, roll, etc., because it is a semi-cylindrical smooth convex arc surface and a concave portion with smooth convex arc surface and curved surface during molding. The appearance of is a log cabin style, which has a decorative effect not seen in conventional products, and when the space on the back side of the surface material is filled with a heat insulating material, the male and female connecting parts of the surface material are The heat insulating material is filled even in the male and female side projecting parts in the above, and the strength and the heat insulating effect of the part can be further improved, and at the same time, the female projecting part has a thickness larger than that of the male projecting part. Since it is thin, the flexibility of the connecting portion during construction is great and the construction can be easily performed, and the tight fitting property of the portion is also good, the waterproofness, the heat insulating property, etc. are various effects. is there.
